Function Notation and Intrerpretation

After reviewing the basics of linear equations, linear systems of equations and inequalities, and quadratic equations, we are going to step by back and look at the larger idea of function.  Here is Salman Khan's (of Khan Academy) introduction to functions video (you can continue to watch his series on functions by clicking here):
Introduction to functions: An introduction to functions.


Here is the basic presentation of the technical side of functions and function notation that we will be navigating over the next 8-10 days:
Here are the series of conceptual tasks we will be going through over the next week that build the general idea of a function from understanding points to understanding the relationship between two values. Please click on the link below to see or print the class tasks we will be investigating (scaffolded document from Language of Functions and Graphs):
Tasks 1 - 4:  Interpreting Points and Sketching Graphs from Words
Tasks 1 - 4:  Interpreting Functions in Situations

Transformations of Functions and Applications of Systems of Equations

Algebra 2 will be moving into applications of systems of equations that will range from profit, cost, and revenue, to mixtures, to numerical relationships, to planes, trains, and automobiles. It should be a good solid honing of your equation writing skills as well as your ability to manipulate equations. I look forward to lively debate, self-reflection, and solid revisions of you personal approaches as we go through the problem-solving process together. Please find some relevant resources below:

We have also started reading short articles at the beginning of class and hope that connecting math to the everyday newsfeed has been interesting and revealing. Here is what we have been reading and will read!
